SPECIFICATION forming part of Letters Patent No. 248,512, dated October 18, 1881.

A pplication led March 21. 1881.

To all whomy it may concern:

Beit known that I, BYRON V. SEEvERs, of Oskaloosa, in the county of Mahaska and State of Iowa, have invented certain new and useful Improvements in Railway-Oar Heaters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference bein ghad to the accompanyingdrawings, which form a part of this specification, and in which- Figure lis a vertical sectional view. Fig. 2 is an enlarged horizontal sectional view on the line x, Fig. 1. Fig. 3 is an enlarged horizontal sectional view on the line y y, Fig. l. Figl is a horizontal sectional view ofthe chute D on the line z z, Fig. 1; and Fig. 5is a detail view, in perspective, of the grate.

Corresponding parts in the several gures are denoted by like letters of reference.

This invention relates to stoves or heaters designed especially to be used upon railroadcars, although they may also, in many cases, be found usef'ul in stores, offices, and dwellingrooms, and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A represents the body of the stove, which rests upon a base, B, supported upon the floor ofthe car (or room, as the case may be) by an annular liange, C.

D is a down wardly-projecting inverted hopper or chute, having an annular flange, E, by which it rests upon the floor, through an opening, F,in which the body of the said chute eX- tends. The upper end or rim ofthe chute fits within a rim or flange, G, cast or formed upon theunder side of the base, as shown, thus causing the several parts to be nicely jointed together. The chute D is provided at its lower end, which is inclined or beveled, as shown, with a hinged or pivoted cover, H, having rigidly connected thereto an arm or lever, I, projecting rearward of the hinge or pivot, and provided with a ball or weight, J, by which the cover is kept in a closed position.

The arm or lever I may be threaded, as rep- (No model) resented in the drawings, so as to make the weight adjustable at any desired distance from the hinge or fulcrum; or the said weight may be made adjustable by means of an ordinary set-screw.

The weight J is so adjusted upon its rod or arm I that it will overbalance the weightot' the door H on the opposite side of the fulcrum, and thus, by causing the door to bear against the lower rim or opening of chute D, keep it closed; and the farther the weight J is removed from the fulcrum the greater, ot' course, will be the amount of ashes and cinders which the door will sustain before being tilted open by their pressure overcoming the weight of the counterpoise J.

K is a rod, hingedor otherwise secured to the lever I, and passing up through the iioor, above which it is provided with an eye or handle, L. Said rod also has a stud or projection, M, which may be engaged with one of a series ot' perforations, N, in an upright, O, secured upon the door for the purpose of holding` the cover H partly open when required.

The ange E of chute D is provided on diametrically-opposite sides with cut-away portions or notches P, directly above which are located draft-openings Q, capable of being partly or entirely closed by rotary slides or registers R, mounted upon rods S journaled in the sides of chute D and base B, and projecting out through the latter, where they are provided with keys or handles T, by means of which they may be operated so as to regulate the draft.

U is the grate, which is globular or spherical in shape, as clearly represented in Figs. 3 and 5 of the drawings, by reference to which it will be seen that it consists of a hollow ball or globe,V, mounted upon a central axis, W, and having projections X parallel to the axle. Bearings Y Z are provided for the axis of the grate upon the base, and at the lower end of the stove-body, beyond which one end of said axis projects, as shown, so as to'be readily operated by means of an ordinary key or wrench.

VThe body of the stove is provided upon its inside, near its upper end,with a series of projections, A', supporting` a hollow ball, B,which is larger in diameter than the pipe-opening O',

which projects upward from the top of the stove in the usual manner.

The chute D may be set either straight or slantingly, and it may be made angular or 5 jointed when circumstances shall require any such modification in its construction.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood. The ashes will drop from the grate down into the chute,where they will remain until their weight overhalances that of' the ball J, when the door or cover Hwill partly open,thus causing the lowermost ashes, which have had ample time to become cold and dead, to be shaken out by the motion of the cars, or,when the heater is used in a building, by their own gravity, the door H being arranged at a sufieient incline for this purpose.

The draft may be readily regulated by means ofthe devices above described, which may always be readily controlled.

When it is desired to increase the draft, as in kindling fires, the cover H may be retained in a partly or entirely open position by engaging the projection M of rod K with one ofthe perforations N in upright O.

To empty the chute of ashes it is only necessary to open the coverHby means ofthe rod K.

The advantages of' the spherical grate will be readily understood. lt can liever be tilted, like the ordinary grate, so as to cause the fire to drop out. The live coals always have a tendency to drop down toward the sides,where the heat is most effective. It also presents a much larger surface than the ordinary grate, different parts or sections of which are alternately exposed for use, thus preventing it from being readily burned out.

When my improved heater is used in a car, and the latter should by any accident be npset, the ball B will roll down and close the pipe-opening, thus preventing the coals from escaping and setting fire to the car.

Having thus described myinvention, Ielaim and desire to secure by Letters Patent of the United States- 1. The combination, with a stove or heater, of a chute extending down through the fioor to carry offl the ashes, and provided with a hinged counterweighted door, as and for the purpose set forth.

2. The combination, with a stove or heater, of a chute extending down through the fioor, and provided with draft-openings and with a notched flange by which it is supported upon the floor, from the opening in which draft is admitted through the said notched flange, substantall y as described, for the purpose set forth.

3. The combination, with a stove or heater, of a chute extending down through the floor, and provided with a hinged connterweighted door and means for operating the latter and retaining it in a partly-open position, as and for the purpose set forth.

4. The combination, in a stove or heater, of the body A, having inwardly-projecting arms A', supporting the ball or ball-valve B', base B, having flange C and rim G, spherical grate U, chute D, having notched flange E, draftopenings Q, and hinged eounterweighted door H, and mechanism for operating the Iatter,all arranged and operating substantially as and for the purpose herein shown and specified.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
